PAVING BLOCK.

Application filed September 10, '1923. Serial No. 661,920.

To all whom it may concern:

Be it known that I, LOUIS Cox, :1. subject of the King of Great Britain, residing at 42, Clarence Road, Harborne, Birmingham, '5 Warwick, England, have invented new and useful Improvements in Paving Blocks, of which the following is a specification.

This invention relates to paving blocks of the kind in which the wearing surface is" 2 formed with corresponding grooves or recesses for their reception and in some cases lockingrods have been provided passing throu h the block and the lugs on the pa as a Eurther means of keeping the pad se- 2 curely fastened to the block. I

It has also been proposed to provide a concrete paving block with a pre-moulded rubber wearing surface which'is continued down the vertical surfaces of the block and .then turned into the concrete" inthe form of a fin, the underside of the pad also being provided with perforated fins of substantially straight form with rounded ends which fit corresponding recesses in the face of the block. According to my invention-in a pavin block of the kind referred to, I form the rubber or like pad with a series of parallel ribs, and the edges of the pad with con- 40 tinuous side and end downward extensions marrying into the vertical sides of the block and integral with the ribs, wires being threaded transversely of the ribs to obtain a keying effect in theblock and to reinforce the latter.

In a suitable arrangement for carrying out the invention the downward extension on the pad has itslower edge sloped downwards from the outside and the ribs which are of about the same depth as the said extension have lugs thereon for the reception of the keying and reinforcing wires .which have their ends bent downwards.

The ribs may be provided with longitudinal beads to increase the keyin eifeet.

To enable the invention to derstood I will describe it by reference to the accompanying drawing, in which;

Figs 1 and 2 are respectively a longitudinal sectional elevation and a transverse section of a paving block constructed in accordance with the invention.

Figs. 3 and 4 are perspective views showing the improved block grooved under surface.

Fig. 5 is a perspective view showing a mode of laying the said blocks.

a isthe block of wood, concrete, metal or other material and b isthe rubber face or pad applied thereto, 0 indicating the parallel ribson the underside of the said face and which are moulded into the block a.

6 indicates the continuous side and end downward extensions which marry into the vertical sides in the block a, with a sloping lower edge as shown. In this arrangement, projecting longitudinal beads may be formed provided with a e fully un-.

on the ribs 0 to increase the keying efl'ect.

7 indicates the wires threaded transversely through the ribs 0, 0 indicating lugs on the,

latter for the purpose.

As indicated in the drawings the upper surface of the face I) may be studded, grooved or otherwise moulded in any suit: able design to produce studs, grooves, or

projections to prevent side-slip or skidding,

tain a firm hold or grip.

and are rooved or serrated as at h as indlcated in ig. 4.

As roads or the like paved. with the imi proved blocks will be nolseless and dustless, and require no watering, they will be very g and so that pedestrians or horses may obhaving transverse grooves adjoining said rabbet, a resilient pad having 9,; downwardly pro'ecting border flange extending into sal tions on the pad engagin said transverse ooves and a. wire moul ed in said block or holding said resilient pad in place.
